Ohio, assignor of one-half to James Emery Dutton, Poland, OhioApplication March 22, 1937, Serial No. 132,391 2 Claims. I (Cl. 292-347)This invention relates generally to door knobs and an important objectthereof is to provide an elastic shock absorber or cushioning device forknobs now in general use, as well as a knob 5 formed from elasticmaterial such as rubber, to prevent defacing or damage to the plaster orpaneling of the wall, disposed in the path of the knob. Therefore itwill be obvious that by the use of my cushioning device, door stops nowgenerally employed can be obviated and the disadvantageous featuresthereof eliminated.

Afurther object is to provide shock absorbers or cushioning devices, forthe purpose set forth thatcan be readily applied, are simple in conl5struction, inexpensive to manufacture in any color, to harmonize withthe color of the door, its fixtures or the general color scheme of theroom and are extremely efllcient in use and service.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawing where- .in like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a front view of the cover form of my cushioning device fordoor knobs now in general use, and illustrates the same applied to a'knob, as well as an escutcheon plate which may be made of the samematerial and color as the 5 cushioning device to harmonize therewith.

Figure 2 is a sectional view taken approximately on line 2-2 of Figure1,1ooking in the direction of the arrows, and illustrates a bumper plateapplied to'the wall and which is likewise 40 made from cushioningmaterial of a color to harmonize with the cushioning device and theescutcheon plate.

Figure 3 is a sectional view taken through a modified form, in which theentire knob structure with theexception of the attaching-sleeve is madefrom cushioning material.

Figure 4 is a sectional view taken approximately on line 4-4of Figure 3,looking in the direction of the arrows.

Referring to the drawing in detail, and particularly to Figures 1 and 2,the reference numeral I indicates adoor knob of a well known type, and

2 the socketed shank thereof which is secured to the spindle 3 in theusual manner. The cushioning device for the knob as best shown in Figure2 a portion 6 that is in the form of a cover therefor and is made fromelastic material such as rubber to provide a hollow body portion 4 witha sleeve portion 5 extending therefrom for disposal about the shank 2,while the body portion is disposed about the 6 body of the knob, itbeing obvious that the cover is of a size to be stretched about the knobbody and shank to snugly'fit the same in the manner as shown.

The hollow body portion is shaped to provide 10 extends outwardly beyondthe outer face of the knob to provide an air chamber 1, and the outerface of the hollow body portion is preferably of fiat disk shapedformation as at 8, with a plurality of openings 9 therein, so that Ill-the outwardly extending portion 6 provides 'an the door, and the plateI I may likewise be formed or made from elastic material, and of thesame color as the plate Ill and the door knob cover so that they willharmonize with each other. The 30 plate l0 can also be'used as a coverplate for switch boxes and the like of electric fixtures and 1 in thatevent it is provided with openings for the passage of the operatingmeans for the switches.

In Figures 3 and 4 I have illustrated the cush- 35 ioning device in theform of a door knob, in that the body I2 is substantially solid, and thesolid portion is shown as being shaped somewhat similar to the body ofthe door knob of Figure 2.

Formed with and extending from the solid por- 40 tion is a hollow sleeveI3 and mounted therein is a metallic sleeve I 4 which cooperates withthe hollow sleeve to provide the shank of the knob, the metallic sleevehaving a right angle cornered bore therein to receive the spindle i5 andheld accordingly thereon in the usual manner by a set screw I6 thatpasses through the sleeves II and M. The sleeve I4 has formed therewitha flange l1 engageable with the outer edge of the sleeve ii.

The form as shown in Figures 3 and 4 includes a hollow portion. l8providing an air chamber IS, the hollow portion extending outwardlybeyond the solid portionand terminating ina flat disk 5 shaped Iace 20having openings 2| therein to provide air passages, as will be apparent.

The cushioning devices including the cover type for the knob, as shownin Figures 1 and 2, the solid type as shown plate III, as well as theescutcheon plate can be formed from any kind of cushioning material,such as rubber, or compositions suitable for the purpose, and they aremade in any color, so as to harmonize with the color oi. the door, itsfixtures and the general color scheme oi! the room or the like, withinwhile the plates Ill and ii are shown as having beveled outer edges andare rectangular in form, it will of course be understood that they canbe made in any shape and have any suitable decorations thereon.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent,

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.

in Figures 3 and 4, and the which they may be used, and 7 what I claimis: 1. A cushioning device for doors comprising an elastic body shapedto provide a knob for a door and including a. solid portion and a hollowportion, the latter providing an air chamber, said hollow portion havingopenings in the face thereof communicating with the chamber, a sleeveformed on the solid portion, means within the sleeve for fitting thespindle oi the latch of the door, and means for securing the first meansto the spindle and extending through the sleeve.

2. A door knob comprising an elastic body including a solid portion, ahollow portion extending outwardly from the solid portion and providingan air chamber, said hollow portion having a flat face provided withopenings therein communicating with the chambenan elastic sleeve formedon the solid portion and extending therefrom, a metallic sleeve withinthe elastic sleeve and having a bore shaped to fit the spindle of a doorlatch, and said sleeves having an opening therein to receive means forsecuring the knob to the spindle.
